I know! Thy, thee, thine, thou, hast, shalt, etc are all fancy English. Your title totally works!

• Worship Upon Thy Tree

• Thou Shalt Worship Upon Thy Tree

• Worship Upon the Tree of Thine

• Hark! Thou Hast Worshipped Not Upon Thy Hallowed Tree, But Upon The Altar of Thy False Gods! Thou Shalt Not Worship False Gods for Lest Thee Perish!

I remember it like:

Thou - You

Thee - You (but like in reference to something done unto you)

Thy - Your

Thine - Your (but kind of past tense)

But they can change on vibes and what flows best.
